- As the patch-type antenna is directional, it has a beam width property. Therefore,
coverage must be considered in addition to the distance between two products.

- The signal sensitivity for the coverage of the beam width is given in the following
table. The best sensitivity can be achieved at the center-to-center angle
(recommended at the time of installation).

* Note: These data are based on a beam width of 90°.
- The distance “N” and coverage “K” may vary by the antenna characteristics and the
RF output power. See Chapter 6, “Dimensions and Specifications.”
* Note: The distance “N” and angle “K” are based on the measurement in an open
site with no obstacles.
